What is the characteristic of waterproof breathable membrane
Waterproof breathable membrane is laid in the building envelope outside the insulation layer of a functional film, suitable for curtain walls, pressure-type steel plates, steel, masonry and other composite exterior walls and slope roofing, with energy saving, improve the durability of the building.
Waterproof membrane is the use of recyclable environmentally friendly materials, so what is the characteristics of waterproof breathable membrane? Let's get to know it.
One, waterproof breathable membrane main characteristics:
1. Waterproof Breathable Membrane Waterproof: 0.1-1.0 micron pores, diameter of less than 10,000 times times, so that moisture can not pass, effective protection of sensitive components, to avoid liquid erosion, improve product service life.
2. Breathable: microporous aperture is more than 700 times times water vapor, waterproof at the same time, allow the air to pass smoothly, can effectively heat dissipation, prevent the inner wall of the product fog, balance internal and external space pressure.
3. Waterproof Breathable Membrane Dustproof: Microporous channel in the membrane formed a mesh three-dimensional structure, evenly dense micro-pore distribution, so that dust encountered barrier, to achieve effective dust-proof effect, the smallest can catch up to 0.1 micron particles.
4. The pore size of the membrane is larger than the pore size of the surface, and the lateral aperture is also different, and the longitudinal micro-pore is larger than the transverse.
5. Waterproof Breathable Membrane The cross-section of the membrane is a network structure, in the three-dimensional structure of the holes have mesh connectivity, hole inserts, channel bending and other very complex changes, there may be a number of micro-pores to form a channel, there is also a possibility of a micro-hole connected with multiple channels.
2, waterproof breathable membrane Application scope:
Waterproof Breathable Membrane The composite coil is suitable for building roofing waterproof, underground waterproof, ground moisture proof, insulation layer insulation, waterproof decoration of inner wall, seepage control of Water Conservancy dike, canal seepage prevention, Chi Ku anti-seepage, metallurgy, chemical contamination anti-seepage, piping waterproof, mine waterproof etc.
Waterproof Breathable Membrane Application industry: Consumer electronics, outdoor lamps, automotive manufacturing, portable equipment, telecommunications equipment, electronics industry.
Three, waterproof breathable membrane main function:
1: Effective blocking moisture, salinity and other corrosive liquids, so that the equipment sensitive parts of the security leak out of the outdoors.
2: Waterproof Breathable Membrane Contact water, oil and other liquids can quickly regain ventilation.
3: Dense homogeneous microporous distribution at the same time waterproof breathable, can effectively block dust.
4: Waterproof Breathable Membrane Balance pressure to prevent the air and moisture around sealed parts into the body, protect seal integrity.
5: The protective components are not affected by the weather, can withstand water and other liquids soak.
6: Make protected parts easy to clean, not affected by corrosive pollutants, to ensure the performance and service life of components.
7: Waterproof Breathable Membrane Anti-ultraviolet, with very strong chemical inertia, extreme temperature resistance.
8: Thin and lightweight, with good concealment, for the design and production to bring convenience, is waterproof breathable ideal products.
